* memory corruption when skipping over long marker (was attempting to read over end of file)
* also updated internal jpeg macros to be the same as in jpeg lib

note: BPY_class_validate() could come in handy later if we need to check classes for properties/functions but for now there is no point in keeping it in.

- omit render code from this warning (cmake only), until render branch is merged.
- moved -Wunused-parameter warning to apply to all C code in blender (not just ./source/blender), (cmake only).
|
|
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.

size rather then short.
also check if jpeg fails to allocate an imbuf.
|
|
all image formats should be able to load files bigger then 2gig (when its supported)
|
|
callback was not correct, modified now to based on jpeg_mem_src as included
with libjpeg.

tile cache code in imbuf, but it is not hooked up to the render engine.
Imbuf module: some small refactoring and removing a lot of unused or old code
(about 6.5k lines).
* Added a ImFileType struct with callbacks to make adding an file format type,
or making changes to the API easier.
* Move imbuf init/exit code into IMB_init()/IMB_exit() functions.
* Increased mipmap levels from 10 to 20, you run into this limit already with
a 2k image.
* Removed hamx, amiga, anim5 format support.
* Removed colormap saving, only simple colormap code now for reading tga.
* Removed gen_dynlibtiff.py, editing this is almost as much work as just
editing the code directly.
* Functions removed that were only used for sequencer plugin API:
IMB_anim_nextpic, IMB_clever_double, IMB_antialias, IMB_gamwarp,
IMB_scalefieldImBuf, IMB_scalefastfieldImBuf, IMB_onethird, IMB_halflace,
IMB_dit0, IMB_dit2, IMB_cspace
* Write metadata info into OpenEXR images. Can be viewed with the command
line utility 'exrheader'
For the image tile cache code, see this page:

Now it's a bit more robust, tagging images with profiles when they're loaded,
which then get interpreted later on by conversion functions. Just Linear RGB
and sRGB profiles at the moment, same as before.
This commit fixes Martin's problem with EXRs and Multilayer images loading/
saving too dark, and it also makes the sequence editor work correctly with it too.
Also fixes:
[#19647] gamma correction with color management is reset when resetting Curve
[#19454] 2.5: Dither does not work when Color management is enabled

needed to fix jpg error handling to not return control to the library from jpg_error used as error exit. Needed to add structured exception handling (setjmp/longjmp) - not very nice but needed in this case. (Also recommended in example.c from libjpg and used in gimp ;) )

blocks that were previously missed; and b) greatly increase my
ohloh stats!

This is the review of the patch:
[#5485] Invisibly stamp render information into jpg and png files.
by Rob Hausauer (paprmh)
NOTE: I split this patch in 3 part:
1) jpeg support
2) python api
3) sequence plugin
This is the first part, hope finish with the other two tomorrow night.

sprinkle a few 'const char*'s around to remove warnings
about discarding qualifiers in imbuf code.
|
|
in doing this in the first place. (1 conditional vs 1 per loop duh)
Thanks for calling me on this Alexander.
(I didn't actually benchmark it to see but its pretty obvious which is less
work for the computer.)

Basically the check for a type of jpeg was messed up.
I added a imb_is_a_jpeg function since I was working on that bit and
it makes it a little more similar to the other filetypes.
I also changed a switch statement that had the same loop for all
cases, just moved the loop outside of the switch statement.

Credits go to Gernot Ziegler, who originally coded EXR support, and to
Austin Benesh for bringing it further. Kent Mein provided a lot of code
for integrating float buffers in Blender imbuf and ImBuf API cleanup,
and provided Make and Scons and static linking.
At this moment; the EXR libraries are a *dependency*, so you cannot get
the Orange branch compiled without having OpenEXR installed. Get the
(precompiled or sources) stuff from www.openexr.com. Current default is
that the headers and lib resides in /user/local/
Several changes/additions/fixes were added:
- EXR code only supported 'half' format (16 bits per channel). I've added
float writing, but for reading it I need tomorrow. :)
- Quite some clumsy copying of data happened in EXR code.
- cleaned up the api calls already a bit, preparing for more advanced
support
- Zbuffers were saved 16 bits, now 32 bits
- automatic adding of .exr extensions went wrong
Imbuf:
- added proper imbuf->flags and imbuf->mall support for float buffers, it
was created for *each* imbuf. :)
- found bugs for float buffers in scaling and flipping. Code there will
need more checks still
- imbuf also needs to be verified to behave properly when no 32 bits
rect exists (for saving for example)
TODO:
- support internal float images for textures, backbuf, AO probes, and
display in Image window
Hope this commit won't screwup syncing with bf-blender... :/

- added BLI_str[n]casecmp, use instead of regular versions
- rewrote BLI_str[n]casecmp to not be stupid

Basically the deal was on the last fix (multiple opens/closes to a filehandle)
I changed the return values to match other image formats 0=fail and 1 = good
(was 1=fail 0=good before)
I Didn't update the animation code to see this so it was
thinking the first frame failed because it was looking for the old return code.

I standarized the returns on a failed opening of the output file for
the above image formats.
I also cleaned up a couple of warnings.
Kent
|
|
I just fixed indentation (replaced spaces with tabs where needed) and removed
#include config.h stuff from the above files.

Summary: standardized imageformat functions(make function names similar, and
parameters in same order where relavant), small code cleanups, and
added a description of how to add an image format to blender.
Kent
Specifics:
merged png_decode.c and png_encode.c to png.c and cleaned function calls.
fixed some spacing in IMB_imbuf_types.h
casting cleanups:
intern/amiga.c
intern/ham.c
intern/iris.c
Modified switch statements to have a default type to insure values are set:
intern/antialias.c
Initalization of some vars and make types similar.
intern/bitplanes.c
cleaned function calls, and changed if else to if's with return:
intern/jpeg.c
added {}'s in multidemensional arrays.
intern/matrix.h
Made a little cleaner to read, and matched above changes.
intern/readimage.c
intern/writeimage.c

#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
Just need to finish cpp files now :)
